1 Two consecutive fasting blood glucose tests that are equal to or greater than 126 mg/dL. 2  Any random blood glucose that is greater than 200 mg/dL.  An A1c test that is equal to or greater than 6.5 percent. A1c is an easy blood test that gives a three month average of blood sugars.
Benzene is an important organic chemical compound with the chemical formula C 6 H 6. Its molecule is composed of 6 carbon atoms joined in a ring, with 1 hydrogen atom attached to each carbon atom.enzene is used mainly as an intermediate to make other chemicals, above all ethylbenzene, cumene, cyclohexane, nitrobenzene, and alkylbenzene. More than half of the entire benzene production is processed into ethylbenzene, a precursor to styrene, which is used to make polymers and plastics like polystyrene and EPS.
This is because benzene is a carcinogen, which means it's a chemical or agent that can potentially cause cancer. The chemical formula of benzene is C6H6, so it has six carbon (C) atoms and six hydrogen (H) atoms. Its chemical structure can be described as a hexagon ring with alternating double bonds, as shown in this illustration. The chemical structure of benzene shows that for each carbon atom, there is one hydrogen atom. There are three ways to draw the chemical structure of benzene, which you can now see on screen. The illustration on the left (1), shows all the carbon and hydrogen atoms and how they are bonded together.
